High-definition video is
video of higher
resolution and quality than standard-definition. While there is no standardized meaning for
high-definition, generally any video image with considerably more than 480 horizontal lines (North America) or 576 horizontal lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a
high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on
film, a technique which is often known as
filmizing.
